Is there any non aggressive cichlids?
I wanna have a peaceful tank of cichlids that don't fight.

Depends somewhat on the individual fish.
but Usually
Uarus
Severeums
Discus
chocolate cichlids
alot of round type cichlids are usually peaceful (see the pattern)
Angelfish
certain types of acaras
rams
certain types of Geophagus
can all [u]usually [/u] be put in peaceful type community setups.

alot of africans can also be combined to make peaceful setups,maybe someone more into africans can give you some info on them.

I have a tank set up just for African cichlids. Mainly Lake Malawi. The Kennyi, Electric yellows and the socolofi are the most peaceful. The female zebras are very sweet too. The male zebra is much more territorial like any other fish, but he just chases and digs holes. If you don't want too much aggression, stay away from the Auratus. I have 3 females to 1 male just to keep him happy.

Allow atleast 4-5 inches of gravel bed with zebras because they dig deep holes and tunnels throughout the large rock caves. They love to swim in and out of big rocks, lots of tall plants and bushes.

The Mbuna cichlids are the most entertaining fish to watch. Since I put them on the all vegitable diet they require, they really seem to look healthier and brighter. (thank you Junior, Brian, and stilllearnin for making me research this) They come right up to you wagging their tails asking for attention.

Don't put Jeweled cichlids in with these Mbunas. Even though they are African, they have different food requirements and will do better with the American cichlids. You can trust me on that one!

Of all my tanks the Lake Malawi cichlid is my favorite.

Ive always found firemouths to be pretty peaceful,defiently uros,severums,most dwarf cichlids you could also try some port cichlids.
